How Engineering Failure Analysis Identifies Problems in Design
Identifying engineering faults is the step-based approach to discovering the reason behind a breakdown in a part, system, or material. These breakdowns are usually linked to material issues or external factors. Specialists use technical assessments to examine what failed, when it failed, and why, in order to prevent similar issues from reoccurring.
Why Failure Reviews Are Necessary
An investigation aims to establish the behaviour of a component under specific loads, settings, or environments. It is used across many fields where system reliability is essential. Investigators collect observations, inspect the failed parts, and examine the data in context with design expectations. This approach enables accurate conclusions that can support future engineering decisions.
How Failure Is Investigated in Engineering
- Start with collecting all available technical documentation, including drawings and use history
- Look for visual signs of damage or irregular use
- Examine the microstructure using tools such as SEM or optical scopes
- Evaluate tensile properties, contamination, or stress profiles
- Apply engineering models and calculations to link evidence to root cause
- Write a report detailing findings and improvement suggestions

Where Failure Analysis Is Used
Failure reviews are carried out in sectors such as aerospace, nuclear, automotive, and rail. For example, a fractured pipe may require fracture surface analysis, or a collapsed beam may need calculations based on loading conditions. The analysis doesn’t only guide repair—it often leads to updates in material use that reduce cost and improve safety.
How Failure Analysis Supports Operations
These investigations minimise the risk of future faults, strengthen health and safety records, and contribute to better engineering decisions. They also support compliance with standards and provide defensible reports useful in claims or audits. Most importantly, they allow engineering teams to refine procedures based on real-world data.
Frequently Asked Questions
Why do faults get investigated?
When a system stops functioning as expected, shows signs of damage, or poses a safety concern.
Which professionals handle analysis?
Experienced engineers in materials, design, or structural testing lead the process.
What equipment helps with analysis?
Common tools include SEM, tensile test machines, and visual inspection instruments.
How long does a typical case take?
The duration depends on how complex the failure is. It could take a few days or a few weeks.
What do reports include?
Documentation outlining what failed, how it failed, and suggested changes.
